Kungani udinga ukwenza izipele? Phela, imishini ithembeke kakhulu, futhi, ngaphandle kwalokho, kukhona "amafu" angcono ekuthembekeni kunamaseva angokwenyama: ngokucushwa okufanele, iseva "yefu" ingasinda kalula ekuhlulekeni kweseva yengqalasizinda, futhi kusukela. iphuzu lokubuka labasebenzisi besevisi, kuzoba nokugxumela okuncane, okungabonakali kusevisi yesikhathi. Ngaphezu kwalokho, ukuphindwaphindwa kolwazi kuvame ukudinga ukukhokhela isikhathi βesingeziweβ sokucubungula, umthwalo wediski, kanye nethrafikhi yenethiwekhi.
Uhlelo olufanele lugijima ngokushesha, aluvuzi inkumbulo, alunazimbobo, futhi alukho.
-Akwaziwa
Njengoba izinhlelo zisabhalwa abathuthukisi bamaprotheni, futhi ngokuvamile ingekho inqubo yokuhlola, kanye nezinhlelo azivamile ukulethwa kusetshenziswa βizindlela ezingcono kakhuluβ (nazo ngokwazo eziyizinhlelo ngakho-ke aziphelele), abaqondisi bohlelo ngokuvamile kufanele baxazulule izinkinga ezizwakala kafushane kodwa. ngamafuphi: "buyela ukuthi bekunjani", "letha isisekelo ekusebenzeni okujwayelekile", "isebenza kancane - buyela emuva", kanye nentandokazi yami "angazi ukuthi yini, kodwa yilungise".
Ngaphezu kwamaphutha anengqondo avela ngenxa yomsebenzi wokunganaki wabathuthukisi, noma inhlanganisela yezimo, kanye nolwazi olungaphelele noma ukungaqondi kahle kwezici ezincane zezinhlelo zokwakha - okuhlanganisa ukuxhuma kanye nesistimu, okuhlanganisa izinhlelo zokusebenza, abashayeli kanye ne-firmware - kukhona namanye amaphutha. Isibonelo, abathuthukisi abaningi bathembele esikhathini sokusebenza, bakhohlwe ngokuphelele ngemithetho yemvelo, okusengakwazi ukuyigwema ngokusebenzisa izinhlelo. Lokhu kuhlanganisa ukwethembeka okungapheli kwesistimu engaphansi yediski futhi, ngokuvamile, noma iyiphi isistimu engaphansi yokugcina idatha (okuhlanganisa i-RAM kanye nenqolobane yokucubungula!), kanye nesikhathi sokucubungula i-zero ku-processor, kanye nokungabikho kwamaphutha ngesikhathi sokudlulisa kunethiwekhi nangesikhathi sokucutshungulwa iprosesa, kanye ne-network latency, elingana no-0. Akufanele ungawunaki umnqamulajuqu owaziwayo, ngoba uma ungahlangabezani nawo ngesikhathi, kuzoba nezinkinga ezimbi kakhulu kunama-nuances wokusebenza kwenethiwekhi nediski.
Yini okufanele uyenze ngezinkinga ezikhuphuka ngamandla futhi zilengise idatha ebalulekile? Akukho lutho olungathatha indawo yabathuthukisi abaphilayo, futhi akulona iqiniso ukuthi kuzokwenzeka esikhathini esizayo esiseduze. Ngakolunye uhlangothi, amaphrojekthi ambalwa kuphela aphumelele ukufakazela ngokugcwele ukuthi uhlelo luzosebenza njengoba bekuhlosiwe, futhi angeke kwenzeke ukuthi kuthathwe futhi kusetshenziswe ubufakazi kwamanye, amaphrojekthi afanayo. Futhi, ubufakazi obunjalo buthatha isikhathi esiningi futhi budinga amakhono akhethekile nolwazi, futhi lokhu kunciphisa amathuba okusetshenziswa kwabo kucatshangelwa izikhathi zokugcina. Ngaphezu kwalokho, okwamanje asikazi ukuthi singasebenzisa kanjani ubuchwepheshe obushesha kakhulu, obushibhile futhi obuthembeke ngokungenamkhawulo ekugcineni, ukucubungula kanye nokudlulisa ulwazi. Ubuchwepheshe obunjalo, uma bukhona, busesimweni semiqondo, noma - kaningi - kuphela ezincwadini eziqanjiwe zesayensi namafilimu.
Abaculi abahle bayakopa, abaculi abakhulu bayantshontsha.

Izixazululo eziphumelela kakhulu kanye nezinto ezilula ngokumangazayo zivame ukwenzeka lapho imiqondo, ubuchwepheshe, ulwazi, nezinkambu zesayensi ezingahambisani nhlobo lapho uqala nje ukuhlangana.
Isibonelo, izinyoni nezindiza zinamaphiko, kodwa naphezu kokufana okusebenzayo - isimiso sokusebenza kwezinye izindlela siyafana, futhi izinkinga zobuchwepheshe zixazululwa ngendlela efanayo: amathambo angenalutho, ukusetshenziswa kwezinto eziqinile nezilula, njll. imiphumela ihluke ngokuphelele, nakuba ifana kakhulu. Izibonelo ezinhle kakhulu esizibona kubuchwepheshe bethu nazo zibolekwe kakhulu emvelweni: izingxenye ezicindezelwe zemikhumbi kanye nemikhumbi-ngwenya iyisifaniso esiqondile nama-annelids; ukwakha ama-raid arraid kanye nokuhlola ubuqotho bedatha - ukuphindaphinda uchungechunge lwe-DNA; kanye nezitho ezibhanqiwe, ukuzimela komsebenzi wezitho ezahlukene ezivela ohlelweni lwezinzwa oluphakathi (okuzenzakalelayo kwenhliziyo) kanye ne-reflexes - izinhlelo ezizimele ku-intanethi. Yiqiniso, ukuthatha nokusebenzisa izixazululo ezenziwe ngomumo "ikhanda" ligcwele izinkinga, kodwa ngubani owaziyo, mhlawumbe azikho ezinye izixazululo.
Ukube ngangazi lapho oyowela khona, ngabe ngendlale izinhlanga!

Lokhu kusho ukuthi amakhophi ayisipele abalulekile kulabo abafuna:
- Ukwazi ukubuyisela ukusebenza kwamasistimu akho ngesikhathi esincane sokuphumula, noma ngaphandle kwakho nhlobo
- Yenza ngesibindi, ngoba uma kwenzeka iphutha kuhlale kukhona ithuba lokuhlehlisa
- Nciphisa imiphumela yenkohlakalo yedatha yamabomu
Nansi ithiyori encane
Noma ikuphi ukuhlukaniswa akunangqondo. Imvelo ayihlukanisi. Siyayihlukanisa ngoba isilungele kakhulu. Futhi sihlukanisa ngokuya ngedatha esibuye siyithathe ngokunganaki.
- UJean Bruler
Kungakhathaliseki ukuthi iyiphi indlela yokugcina idatha, ukugcinwa kwedatha okunengqondo kungahlukaniswa ngezindlela ezimbili zokufinyelela le datha: vimba kanye nefayela. Lokhu kuhlukaniswa kusanda kufiphala kakhulu, ngoba i-block kuphela, kanye nefayela kuphela, isitoreji esinengqondo asikho. Nokho, ukuze kube lula, sizothatha ngokuthi zikhona.
Vimba isitoreji sedatha sisho ukuthi kukhona idivayisi ephathekayo lapho idatha ibhalwe khona ezingxenyeni ezithile ezingashintshi, amabhlogo. Amabhulokhi afinyelelwa ekhelini elithile; ibhulokhi ngayinye inekheli layo ngaphakathi kwedivayisi.
Ikhophi yasenqolobaneni ngokuvamile yenziwa ngokukopisha amabhulokhi edatha. Ukuqinisekisa ubuqotho bedatha, ukurekhodwa kwamabhulokhi amasha, kanye nezinguquko ezikhona kakade, kumisiwe ngesikhathi sokukopisha. Uma sithatha isifaniso esivela emhlabeni ojwayelekile, into eseduze kakhulu yikhabethe elinamaseli anezinombolo ezifanayo.
Isitoreji sedatha yefayela esisekelwe kumgomo wedivayisi enengqondo siseduze nokugcinwa kokuvinjwa futhi ngokuvamile sihlelwa phezulu. Umehluko obalulekile ubukhona besigaba sesitoreji namagama afundeka abantu. I-abstraction inikezwa ngendlela yefayela - indawo yedatha ebizwa ngokuthi, kanye nohla lwemibhalo - ifayela elikhethekile lapho kugcinwa khona izincazelo nokufinyelela kwamanye amafayela. Amafayela anganikezwa imethadatha eyengeziwe: isikhathi sokudala, amafulegi okufinyelela, njll. Izipele ngokuvamile zenziwe ngale ndlela: zibheka amafayela ashintshiwe, bese zikopishela kwesinye isitoreji sefayela ngesakhiwo esifanayo. Ubuqotho bedatha ngokuvamile busetshenziswa ukungabi khona kwamafayela abhalelwa kuwo. Imethadatha yefayela yenziwa ikhophi yasenqolobaneni ngendlela efanayo. Isifaniso esiseduze kakhulu umtapo wezincwadi, onezigaba ezinezincwadi ezihlukene, futhi unekhathalogi enamagama ezincwadi afundeka abantu.
Muva nje, enye inketho ichazwa ngezinye izikhathi, lapho, ngokuyisisekelo, isitoreji sedatha yefayela yaqala, futhi enezici ezifanayo zakudala: ukugcinwa kwedatha yento.
Ihluke ekugcinweni kwefayela ngoba ayinaso isidleke esingaphezu kwesisodwa (i-flat scheme), futhi amagama amafayela, nakuba efundeka abantu, asafaneleka kakhulu ukucutshungulwa ngemishini. Lapho wenza izipele, ukugcinwa kwento kuvame ukuphathwa ngendlela efanayo nokugcinwa kwamafayela, kodwa ngezinye izikhathi kuba nezinye izinketho.
- Kunezinhlobo ezimbili zabaphathi besistimu, labo abangawenzi amakhophi ayisipele, kanye nalabo ABANGASE bekwenzile.
- Empeleni, kunezinhlobo ezintathu: kukhona nalabo abahlola ukuthi izipele zingabuyiselwa.-Akwaziwa
Kuyafaneleka futhi ukuqonda ukuthi inqubo yokwenza isipele idatha ngokwayo yenziwa izinhlelo, ngakho-ke inezinkinga ezifanayo njenganoma yiluphi olunye uhlelo. Ukususa (hhayi ukuqeda!) ukuncika kusici somuntu, kanye nezici - ezithi ngabanye azinawo umthelela oqinile, kodwa ndawonye zinganikeza umphumela obonakalayo - okuthiwa umthetho 3-2-1. Kunezinketho eziningi zendlela yokuyisusa, kodwa ngithanda ukuhumusha okulandelayo: udinga ukugcina amasethi angu-3 edatha efanayo, amasethi angu-2 adinga ukugcinwa ngefomethi ehlukene, futhi isethi engu-1 kufanele igcinwe endaweni yokugcina ekude yendawo.
Ifomethi yesitoreji kufanele iqondwe ngale ndlela elandelayo:
- Uma kukhona ukuncika endleleni yokugcina impahla, sishintsha indlela ebonakalayo.
- Uma kukhona ukuncika endleleni yokugcina enengqondo, sishintsha indlela enengqondo.
Ukuze uzuze umphumela omkhulu womthetho we-3-2-1, kunconywa ukuthi uguqule ifomethi yesitoreji ngezindlela zombili.
Ngokombono wokulungela ikhophi yasenqolobaneni ngenjongo yayo ehlosiwe - ukubuyisela ukusebenza - kwenziwa umehluko phakathi kwezipele "ezishisayo" kanye "ezibandayo". Okushisayo kwehluka kokubandayo entweni eyodwa kuphela: zilungele ukusetshenziswa ngokushesha, kanti ezibandayo zidinga izinyathelo ezengeziwe zokululama: ukukhishwa kwekhodi, ukukhishwa kusuka kungobo yomlando, njll.
Ungaphambanisi amakhophi ashisayo nabandayo namakhophi aku-inthanethi nangaxhunyiwe ku-inthanethi, okusho ukuhlukaniswa ngokomzimba kwedatha futhi, empeleni, olunye uphawu lokuhlukaniswa kwezindlela zokulondoloza. Ngakho-ke ikhophi engaxhunyiwe ku-inthanethi - engaxhunywanga ngokuqondile ohlelweni lapho idinga ukubuyiselwa khona - ingaba ishise noma ibanda (ngokwemibandela yokulungela ukutholwa). Ikhophi eku-inthanethi ingatholakala ngokuqondile lapho idinga ukubuyiselwa khona, futhi ngokuvamile kushisa, kodwa kukhona namakhaza.
Ngaphezu kwalokho, ungakhohlwa ukuthi inqubo yokwenza amakhophi ayisipele ngokwayo ngokuvamile ayigcini ngokudala ikhophi eyodwa yokusekelayo, futhi kungaba nenani elikhulu lamakhophi. Ngakho-ke, kuyadingeka ukuhlukanisa phakathi kwama-backups agcwele, i.e. lawo angabuyiselwa ngokuzimela kwezinye izipele, kanye namakhophi ahlukanisiwe (akhuphukayo, ahlukanisiwe, anciphayo, njll.) - lawo angakwazi ukubuyiselwa ngokuzimela futhi adinga ukubuyiselwa kokuqala kwekhophi eyodwa noma ngaphezulu.
Izipele ezikhulayo ezihlukile ziwumzamo wokulondoloza indawo yokugcina ikhophi yasenqolobaneni. Ngakho, idatha eshintshiwe kuphela evela kukhophi yasenqolobaneni yangaphambili ibhalwa ekhophi eyisipele.
Okuncishiswayo okuhlukile kudalelwa inhloso efanayo, kodwa ngendlela ethe ukuhluka: kwenziwa ikhophi eyisipele egcwele, kodwa umehluko kuphela phakathi kwekhophi entsha nedlule ogcinwa empeleni.
Ngokwehlukana, kufanelekile ukucabangela inqubo yokwenza ikhophi yasenqolobaneni phezu kwesitoreji, esekela ukungabikho kokugcinwa kwezimpinda. Ngakho-ke, uma ubhala izipele ezigcwele phezu kwayo, umehluko kuphela phakathi kwama-backups uzobhalwa ngempela, kodwa inqubo yokubuyisela ama-backups izofana nokubuyisela kusuka kukhophi egcwele futhi obala ngokuphelele.
Ingabe i-custodiet ipsos custodes?
(Ubani ozogada abalindi ngokwabo? - lat.)
Akujabulisi kakhulu uma engekho amakhophi ayisipele, kodwa kuba kubi kakhulu uma ikhophi eyisipele ibonakala sengathi yenziwe, kodwa uma uyibuyisela kuvela ukuthi ayikwazi ukubuyiselwa ngoba:
- Ubuqotho bedatha yomthombo busengozini.
- Isitoreji sokulondoloza sonakele.
- Ukubuyisela kusebenza kancane kakhulu; awukwazi ukusebenzisa idatha ebuyiselwe ngokwengxenye.
Inqubo yokwenza isipele eyakhiwe kahle kufanele icabangele ukuphawula okunjalo, ikakhulukazi okubili kokuqala.
Ubuqotho bedatha yomthombo bungaqinisekiswa ngezindlela ezimbalwa. Okuvame ukusetshenziswa kakhulu yilokhu okulandelayo: a) ukudala izifinyezo zesistimu yefayela ezingeni lokuvimba, b) "ukuqandisa" isimo sesistimu yefayela, c) idivayisi ekhethekile yokuvimba enesitoreji senguqulo, d) ukuqoshwa okulandelanayo kwamafayela noma amabhlogo. Amasheke nawo asetshenziswa ukuze kuqinisekiswe ukuthi idatha iyaqinisekiswa ngesikhathi sokutholwa.
Ukonakala kwesitoreji nakho kungatholwa kusetshenziswa amasheke. Indlela eyengeziwe ukusetshenziswa kwamadivayisi akhethekile noma amasistimu wefayela lapho idatha erekhodiwe kakade ingenakushintshwa, kodwa emisha ingengezwa.
Ukusheshisa ukululama, ukutholwa kwedatha kusetshenziswa nezinqubo eziningi zokuthola kabusha - inqobo nje uma kungekho ibhodlela ngesimo senethiwekhi enensayo noma uhlelo lwediski olunensayo. Ukuze uzungeze lesi simo ngedatha ebuyiselwe kancane, ungahlukanisa inqubo yokwenza isipele ibe imisebenzi engaphansi emincane uma kuqhathaniswa, ngamunye owenziwa ngokuhlukene. Ngakho-ke, kuba nokwenzeka ukubuyisela ukusebenza ngokuqhubekayo ngenkathi ubikezela isikhathi sokutakula. Le nkinga ivame ukutholakala endizeni yenhlangano (SLA), ngakho-ke ngeke sigxile kulokhu ngokuningiliziwe.
Uchwepheshe wezinongo akuyena owengeza kuzo zonke izitsha, kodwa lowo ongalokothi engeze okunye kukho.

Imikhuba ephathelene nesofthiwe esetshenziswa abalawuli besistimu ingase yehluke, kodwa imigomo evamile isafana, ngendlela eyodwa noma enye, ikakhulukazi:
- Kunconywa kakhulu ukusebenzisa izixazululo ezenziwe ngomumo.
- Izinhlelo kufanele zisebenze ngokubikezela, i.e. Akufanele kube khona izici ezingabhaliwe noma izingqinamba.
- Ukusetha uhlelo ngalunye kufanele kube lula kangangokuthi akudingeki ukuthi ufunde imanuwali noma ishidi lokukopela njalo.
- Uma kungenzeka, ikhambi kufanele libe yindawo yonke, ngoba amaseva angahluka kakhulu ezicini zawo zehadiwe.
Kukhona izinhlelo ezilandelayo ezijwayelekile zokuthatha amakhophi asenqolobaneni kumadivayisi avinjiwe:
- dd, ejwayele omakadebona bokuphatha uhlelo, lokhu kuhlanganisa nezinhlelo ezifanayo (isibonelo dd_rescue efanayo).
- Izinsiza ezakhelwe kwezinye izinhlelo zefayela ezidala ukulahlwa kwesistimu yefayela.
- Izinsiza ze-Omnivorous; isibonelo i-partclone.
- Izinqumo ezingokwakho, ngokuvamile ezingezobunikazi; isibonelo, NortonGhost futhi kamuva.
Kuzinhlelo zefayela, inkinga yokusekelayo ixazululwa kancane kusetshenziswa izindlela ezisebenzayo kumadivayisi we-block, kodwa inkinga ingaxazululwa ngokuphumelelayo ngokusebenzisa, isibonelo:
- I-Rsync, uhlelo lwenhloso evamile kanye nephrothokholi yokuvumelanisa isimo sezinhlelo zamafayela.
- Amathuluzi okugcina umlando owakhelwe ngaphakathi (ZFS).
- Amathuluzi okugcina umlando womuntu wesithathu; ummeleli odume kakhulu yitiyela. Kukhona abanye, isibonelo, i-dar - indawo yetiyela okuhloswe ngayo izinhlelo zesimanje.
Kuyafaneleka ukubalula ngokwehlukana ngamathuluzi esofthiwe okuqinisekisa ukuvumelana kwedatha lapho udala amakhophi ayisipele. Izinketho ezisetshenziswa kakhulu yilezi:
- Ukukhweza isistimu yefayela kumodi yokufunda kuphela (ReadOnly), noma ukufriza isistimu yefayela (iqhwa) - le ndlela iyasebenza okulinganiselwe.
- Ukudala izifinyezo zesimo sezinhlelo zamafayela noma amadivayisi wokuvimba (i-LVM, i-ZFS).
- Ukusetshenziswa kwamathuluzi ezinkampani zangaphandle ukuhlela okuvelayo, ngisho nasezimeni lapho amaphuzu adlule engakwazi ukuhlinzekwa ngesizathu esithile (izinhlelo ezifana ne-hotcopy).
- Indlela yokukopisha ekushintsheni (CopyOnWrite), nokho, ivamise ukuboshelwa ohlelweni lwefayela olusetshenziswa (BTRFS, ZFS).
Ngakho-ke, kuseva encane udinga ukuhlinzeka ngohlelo lokulondoloza oluhlangabezana nalezi zidingo ezilandelayo:
- Kulula ukuyisebenzisa - azikho izinyathelo ezikhethekile ezengeziwe ezidingekayo ngesikhathi sokusebenza, izinyathelo ezincane zokudala nokubuyisela amakhophi.
- I-Universal - isebenza kuzo zombili iziphakeli ezinkulu nezincane; lokhu kubalulekile lapho ukhulisa inani lamaseva noma ukukala.
- Kufakwe umphathi wephakeji, noma kumyalo owodwa noma emibili njengokuthi βlanda futhi ukhipheβ.
- Izinzile - kusetshenziswa ifomethi yesitoreji esejwayelekile noma esenesikhathi eside.
- Ngokushesha emsebenzini.
